A personal stash in the carry-on? Never a good idea.

The X Factor-birthed girl group Fifth Harmony, known for smash hits like "Work from Home," is set to perform in Brazil tonight at Vevo's Fun Pop Festival, though only four of the five members were able to make the trip, as 20-year-old Lauren Jauregui was arrested at the airport for marijuana possession, reports TMZ. According to law enforcement sources, Jauregui was stopped at security on Tuesday night and forced to submit to a secondary search, whereupon a TSA staff member found a bag of marijuana in her carry-on luggage.

Cops were called to the scene and Jauregui was promptly arrested, while in the company of the rest of Fifth Harmony. She was later released on a summons, as confirmed to PEOPLE by a Metropolitan Washington Airports Authority spokeswoman. It is currently unclear how Jauregui's ability to travel with her group will be affected by last night's arrest. Neither Jauregui nor Fifth Harmony have spoken on the incident.
